Tecmate OptiMATE MONITOR O-127 Permanent power sport battery lead with integrated battery status/charge system monitor for 12.8/13.2V lithium.

Exactly what I needed. Took all of 3 minutes to install and makes keeping the batter charged super easy. Pull up in the garage and just plug it in. When I'm ready to go I just unplug it and let it hang under the seat, just inside the frame. The build quality is far better than I expected for the price and the colored lights letting you know the status are a nice touch.

I really like this device for my motorcycles. One look and you can see if the battery is ready to go.

Nice charger extension. This addition makes charging the battery much easier.

Bought this to leave permanently on the car to make it easier to top up the battery during the winter months. This lead has a LED light strip on it which tells you at a glance what the battery state of charge is. The lead is robust and it comes with a velcro strap to help pin the head unit to something rather than have it flapping about on top of the battery. Quality piece of kit.
